and a first remote display device comprising: a transceiver to receive a wireless signal from the medical device; a camera to capture a video feed; a screen; and a processor to perform operations to: display, on the screen, the video feed; overlay an alignment element on the video feed, the alignment element indicating a target position for the visual marker on the medical device to be disposed within to initiate a pairing procedure; measure a signal strength of the wireless signal; and pair the first remote display device with the medical device when the signal strength exceeds a threshold signal strength, wherein the threshold signal strength is exceeded when the visual marker on the medical device is in the target position. ### Claim 2 (depends on 1) The system of claim 1, wherein the medical device comprises a pressure sensor, and a transmitter in communication with the sensor and configured to transmit a wireless signal representative of data from the sensor. ### Claim 3 (depends on 2) The system of claim 2, the processor is further to perform operations to display the data from the sensor. ### Claim 4 (depends on 3) The system of claim 3, further comprising a second remote display device to display the data from the sensor. ### Claim 5 (depends on 4) The system of claim 4, wherein the first remote display device sends the data from the sensor to the second remote display device. ### Claim 6 (depends on 4) The system of claim 4, wherein the first remote display device and the second remote display device receive the wireless signal representative of data from the sensor. ### Claim 7 (depends on 4) The system of claim 4, wherein the second remote display device receives pairing information associated with the medical device from the first remote display device to facilitate pairing of the second remote display device with the medical device. ### Claim 8 (depends on 1) The system of claim 1, wherein the processor is further to perform operations to determine a size for the alignment overlay based on a lens aperture of the camera, a sensor size of the camera, and the threshold signal strength. ### Claim 9 (depends on 1) The system of claim 1, wherein the medical device further comprises a light emitting diode (LED) to indicate a state of the medical device, wherein an off state is indicated by the LED being off, an advertising state is indicated by the LED flashing, a paired state is indicated by the LED being solid, and an error state is indicated by the LED flashing faster than when in the advertising state. ### Claim 10 (depends on 1) The system of claim 1, wherein the visual marker comprises a machine-readable optical label. ### Claim 11 (depends on 10) The system of claim 10, wherein the processor is further to perform operations to scan the machine-readable optical label to obtain information about the first remote display device. ### Claim 12 (depends on 1) The system of claim 1, wherein the medical device comprises a temperature sensor. ### Claim 13 (depends on 1) The system of claim 1, wherein the medical device comprises: a body component; a pressurization component configured to increase or decrease pressure within the body component by displacing the pressurization component with respect to the body component; an actuator operably connected to the pressurization component and configured to displace the pressurization component with respect to the body component; and a sensor that tracks displacement of the pressurization component to determine volume of a liquid displaced by the pressurization component. ### Claim 14 A method for wirelessly coupling a remote display device to a medical device, the method comprising: capturing an image stream with a camera associated with the remote display device; displaying the image stream on the remote display device; overlaying an alignment frame on the image stream for alignment of the remote display device with to the medical device for pairing, wherein for alignment a user positions the camera such that images of a visual indicator on the medical device are within the alignment frame on the remote display device; measuring a signal from the medical device with the remote display device to determine a signal strength; and pairing the remote display device with the medical device when the signal strength exceeds a threshold signal strength, wherein alignment of the visual indicator within the alignment frame causes the medical device to be positioned such that the threshold signal strength is exceeded. ### Claim 15 (depends on 14) The method of claim 14, wherein the visual indicator comprises a quick response code. ### Claim 16 (depends on 14) The method of claim 14, wherein measuring the signal comprises determining a received signal strength indicator. ### Claim 17 (depends on 14) The method of claim 14, further comprising: receiving a wireless signal representative of a pressure measured by a pressure sensor on the medical device; and displaying the pressure on the remote display device. ### Claim 18 (depends on 17) The method of claim 17, further comprising storing the pressure measured by the pressure sensor on a remote server. ### Claim 19 An inflation device configured for use with a medical device, the inflation device comprising: a body component configured to house a bone cement; a pressurization component configured to increase or decrease pressure within the body component by displacing the pressurization component with respect to the body component; an actuator operably connected to the pressurization component and configured to displace the body component; a pressure sensor in communication with the body component and configured to measure pressure within the body component; a temperature sensor configured to measure a temperature of the bone cement in the body component; a volume sensor that tracks displacement of the pressurization component to determine an amount of bone cement displaced by the pressurization component; and a transmitter in communication with the pressure sensor, the temperature sensor, and the volume sensor, the transmitter configured to transmit a wireless signal representative of the pressure measured by the pressure sensor, the temperature measured by the temperature sensor, and the amount of bone cement displaced measured by the volume sensor to a remote display device that is configured to determine a life window of the bone cement based on the transmitted pressure, temperature, and amount of bone cement displaced. ### Claim 20 (depends on 19) The inflation device of claim 19, further comprising a viscosity sensor to measure the viscosity of the bone cement in the body component.
